STYLOGRAPHIC FOUNTAIN-PEN.

SPECIFICATION forming part Of Letters :Patent N0. 233,106, dated001301381* 12, 1880.

' Application filed August 7, 1880. (No model.)

York, have inventedaV new and Improved Stylographie Pen, of which thefollowing is a specification.

Figure 1 is a side `view oi' niyimproved stylographic pen, and Fig. 2 isa central longitudinal section thereof.

eilicient and easily-regulated construction of stylographic pen;` and itconsists in extending the stern which carries thc writing-spindlethrough the entire length of the apparatus, in cushioning it near theupper end, in combining it with a peculiar'iller and air-tube, inproviding it below saidtube with a valve for closing the latter, and inother details ot i111- proveinent hereinafter more fully pointed out.

In the accompanying drawings, theletterA represents the shell of thepen, which may be made ot' glass, hard rubber, or any other suitablematerial. To the lower end of this shell is secured the ink-dischargenipple B, through which the writing-spindle C prot-rudes. Said spindle Cis a tine-wire coil at its upper portion, as shown at a, and fitted byits coil part upon a stem or rod, D', which is grooved, roughened, ornotched at the lower part to hold the coil portion properly in place.rIhe roughenin g of the lower part of stem D is not illustrated.

By this construction I am enabled to secure the writing-spindle upon thestem by merely slipping its coil portion oft', thereby allowing itsleasy replacement when worn, and enabling me to supply each pen with aseries of said spindles, either one ot' which theowner may use.. The`spindle C can be lengthened by stretching the coil. l

The stem-D is screw-threaded, except at its ends, and a short distancebelow its upper end a collar, b, is screwed to it. Above this collar isa spring, d, which bears against the under side ot' the turned-in'iiangee of the filling-tube E. This lilling-ltube, which also serves as anair-tube to discharge the ink in writing, has a screw-threadedouterportion, f, that is screwed into the uppenen'd of the shell A, sothat thus the shell A is closed dil top by the iilling-tube, which tube,moreover, guides the stem D, `holds it centrally, and allows" it aslight up- The plate h embraces the stem D, and is itself v 1 held fastby a suitable clasp, z', that engages This invention relates to a verysimple and' spindle G out of the shell A, allowing the latter tobereadily repaired or replaced 1f the stem is to be detached from theller'tube, the 'plate h is unfastened, so as to allow the stem to bedrawn downward out of said tube. The

filler-tube is used for filling by dipping its lower portion into aninkreservoir, and then carrying the supply it contains to the shell,

holding the upper opening ot' the ller-tube.

closed with the linger until the tube E is over the shell, when thetinger is removed and the ink can tlow into the shell. The rings jretain some ofthe ink, into which the tube is dipped, and show therebythe depth to which the tube was inserted, which otherwise could not beconveniently ascertained, and by thismeans the user is enabled toregulate the snpply of ink with great nicety.

Should the ink-bottle from which the supply is to'be obtained be toodeep and the ink too low therein to use the ller, the inl; can be drawnby gentle suction ofthe lips directly through4 the aperture in the lowerend of A into A, and by inserting filler E into A to thel highest ringthereon. The depth of the ink taken intotube A can be ascertained by thewetting ot' sides of B, and can be allowed, if in excess, to escape tothe proper amount-as, e, g., so many drops for ink found betweensuccessive spaces between the rings.

When the pen is put together, as shown in Fig. 2, and supplied with ink,it can be used IOO in writinglike any other stylographc pen. If 2. Thestem D, carrying the Writing-spindle the writer desires to pnt the peninto his pocket, and to prevent the ink from tiowing into the tube E,and thence penetrating into the pocket, he first pulls the stem I)upward so as to close the valve k against the lower end of the llngtllbeand catch the springclasp i, attached to plate h, into the lower groove,1 ofthe rod D. This also retracts the writing end of C into A andpreserves it from breaking. The peu is then inverted, causing the ink inthe shell to How into the space which surrounds the filling-tube, and toremain there While inverted (in which position it should be in thepocket) without having: an opportunity to flow into the filling-tube.

Should the pen choke in writing, :1s often happens in st vlographicpens. the style-rod I) is seized at the upper projectingr end and workedback and forth till obstruction is removed.

I claim- 1. A Stylographic pen composed ol` a shell, A, filler andair-tube I1,and stem l), the stem carrying the writing-spindle and beingattached to the tube l'l, all arranged so that an air-space surroundsthe stem within and along the tube E, substantially as described.

and provided with a projecting collar, b, in combination with the springd, which bears upon said collar, and with the inwardly-turned tiange conthe inserted filling-tube E above said spring, substantially asdescribed.

3. The combination of the cushion g with the plate h, clasp i, stem D,and filler and airtnbe E, snbstantiallyas shown and described.

4. The combination of the shell A, filler and air'tube E, movable stemD, Writing-spindle C, and valve 1.-, for operation substantially asdescribed.

5. The filler and air-tube E, constructed with the embracingr andprojecting rings j, substan tiallv as and for the purpose specified.

6. The combination of' the stem 1), carrying the spindle (j, and havingnotches 1 and 2 above the tube A, with the clasp i, also above said tubeA, and with the air-tube E. said clasp serving to properly hold thespindle C either in the lower working position or elevated,substantiall)v as herein shown and described.
